Explanation of terms
Interactive DVD
With this DVD disc, the story is changeable by
user's selection, and/or the direction of view is
changeable.
Title, chapter (DVD)
A DVD disc is divided into large parts (title) and
smaller parts (chapter).
Each part has a number which is called title
number or chapter number.
OPT OUT jack
The OPT OUT jack changes electric signals into
optical signals before transmitting them to the
amplifier. According to this, the signals flow
without electric effect from outside, and noise is
suppressed and produces little effect for
outside.
Track (video CD/audio CD)
A video CD or an audio CD is divided into some
parts (track).
Each part has a number which is called a track
number.
Dolby digital (AC-3)
A technique for digital audio compression
developed by Dolby Corporation.
Not only stereo (2 ch) sound, but also 5.1 ch
sound can be compressed by it. A large
amount of data can be held in a disc efficiently.
Dolby pro logic decoder
Equipment in which 4 channel signals recorded
in 2 channels by dolby surround (pro logic) are
reverted to signals in 4 channels when playing
them back. As compared with the surround
sounds of 5.1 ch of dolby digital (AC-3),
separation between channels is worse and
surround signal is played back only within 7
kHz.
Pan & scan screen
This signifies that the screen recorded in wide­
screen format is displayed with left and right
portions cut off.
Playback control (video CD Version 2.0)
A video CD with the playback control function
can be played back by following the menu
display interactively.
Letter box screen
This signifies that the screen recorded in wide­
screen format is displayed with black bands at
the top and bottom of the screen.
Linear PCM audio (LPCM)
This is the signal recording system for audio
CD.
While the signals are recorded by 44.1 kHz/16
bit in audio CD, by 48 kHz/16 bit - 96 kHz/24 bit
in DVD. As a result, DVD is played back in
higher quality sound than in audio CD.
MPEG (Moving Picture Experts Group)
MPEG is the international standard format for
moving pictures provided by the Moving Picture
Experts Group organized under ISO
(International Organization for Standardization)
and IEC (International Electro-technical
Commission). MPEG provided MPEG1 in 1991,
and MPEG2 in 1994. MPEG2 enables play in
higher quality than MPEG1.
S-VIDEO OUT terminal
As this terminal divides the video signals into
color signal and brightness signal to transmit
them to the TV set, the picture becomes clearer.
We recommend connecting an S-VIDEO cord
(supplied) to the TV set and S-VIDEO terminal.
